My friends that have a TiVo never watch live TV.

Ditto that, my wife and very very rarely watch live TV. Probably the only time I will is when I've watch all of the Dr. Whos and what not, and the only thing left is my wife's Oprahs. (blech)

I don't know if this has been posted, but I'll give it a shot...

I've accumulated well over a thousand bookmarks and have been much too lazy to organize them into folders. If you could automatically cluster bookmarks (http://vivisimo.com/ does this with web results) I would be eternally grateful.

One more suggestion is to learn usage patterns in a particular website. For example, when I go to http://www.nytimes.com, I generally click on the opinions sections. If the browser could anticipate that I typically go to the opinion section, it could start to preload it before I click on it.

I realize the later suggestion is much easier to implement than the former, but the clustering would be very useful for lazy surfers like me.

If you look at the Kawa package, which produces Java bytecodes from the scheme language, you find that exactly this problem. Scheme continuations cannot be fully expressed as Java bytecodes, so you can't use them and still produce runnable Java programs. CLR will have the same limitations.
